A system and method for manufacturing a brushless direct current (BLDC) motor fluid pump is disclosed. The system includes an electromagnetic forming device, an upper fixture, a lower fixture, and a pneumatic or hydraulic cylinder. The electromagnetic forming device has a central cavity. The central cavity has a predefined depth from an outer surface of the electromagnetic forming device. The upper fixture is disposed in the central cavity. The upper fixture has a pump stop surface that contacts the BLDC motor fuel pump, and the pump stop surface is selectively spaced from the outer surface of the electromagnetic forming device. A lower fixture having a central cavity for receiving the housing of the BLDC motor fluid pump is provided. A cylinder is configured to move the lower fixture towards the upper fixture until the pump stop surface of the upper fixture contacts the BLDC motor fluid pump. The electromagnetic forming device is activated to seal the housing of the pump assembly once the pump assembly is properly positioned within the magneforming device.
